Strengthened Steel(강화된 강철)란 무엇입니까?
Strengthened Steel 강화된 강철 - Oxide dispersion-strengthened steels prevent M23C6 precipitation by reducing C content to increase creep life and introduce a high density of nano-sized oxide precipitates to offset the reduced strength. [1] We found that combining the key features of nanocrystalline steels and oxide dispersion-strengthened steels, NC304-La showed excellent bubble swelling resistance. [2] The basis of the study is the development of a new analytical method for the prediction of the moment-curvature relationship and the overall flexural response of FRP-strengthened steel-concrete beams, by assuming perfect bond between the constitutive components. [3] Research on the bond performance of CFRP-strengthened steel have been done for the past years, but it has mainly focused on lower grades of steel. [4]산화물 분산 강화강은 C 함량을 감소시켜 크리프 수명을 증가시키고 감소된 강도를 상쇄하기 위해 고밀도 나노 크기 산화물 침전물을 도입함으로써 M23C6 침전을 방지합니다. [1] 나노결정질강과 산화물분산강화강재의 주요 특성을 결합한 NC304-La는 우수한 기포팽윤 저항성을 나타냄을 확인했습니다. [2] 연구의 기초는 구성 요소 사이의 완벽한 결합을 가정하여 FRP 강화 철골 콘크리트 보의 모멘트-곡률 관계 및 전체 휨 응답을 예측하기 위한 새로운 해석 방법의 개발입니다. [3] CFRP 강화강의 접착성능에 대한 연구는 지난 몇 년간 진행되어 왔지만 주로 저급강에 집중되어 왔다. [4]

The bond-slip model of a carbon fiber reinforced polymer (CFRP)-steel bonded interface is crucial for predicting the bond behavior of CFRP-strengthened steel structures. [1] Shear and normal stresses intensity are two important factors which cause Carbon Fiber Reinforced Polymer (CFRP) end debonding in strengthened steel beams. [2] The viscoelastic constitutive relation for adhesives is described using the modified Maxwell model to study the influences of the viscoelastic constitutive relation of adhesives and of the design parameters of carbon fiber reinforced polymer (CFRP)-strengthened steel beam on CFRP-to-steel interfacial stresses. [3] , carbon fiber reinforced polymer (CFRP) strengthened steel/concrete beams) has always been an important problem urgent to be solved. [4] The bond-slip degradation relationship of a carbon fiber reinforced polymer (CFRP)-steel bonded interface is crucial for predicting the long-term behavior of CFRP-strengthened steel structure under a freeze-thaw (F-T) environment.
